SPECIFICATION forming part of Letters Patent No. 477,251, dated June 21, 1892. Application filed February 12, 1892. Serial No. 421,274. (No model.)

To all whom it may concern.-

Be it known that I, HERBERT P. EWELL, a citizen of the United States, residing at Rochester, county of Oakland, State of Michigan, have invented a certain new and useful Improvement in Trusses; and I declare the followingto be a full, clear, and exact description of the same, such as will enable others skilled in the art to which it pertains to make and use the same, reference being had to the accompanying drawings, which form a part of this specification.

My invention relates to trusses, and has for its object the provision of a coiled-spring pad and its supporting-band so arranged and connected that the pad is kept in position on the person. It is found to be desirable to use these spring-pads without any covering and that, owing to the shape of the pad, especially when so used, it will work out from under the hand and roll downward as the body is moved. This is due to the fact that the body is bent forward in most of its movements, and the tendency is to force the pad downward and out of position. My construction is designed to remedy this difficulty and always hold the pad in position or to aid in returning it when displaced.

In the drawings, Figure l is a view of the truss with the spring-pad and the other attachments. Fig. 2 is a side elevation of the pad, showing the form of the extension across the base. Fig. 3 is a detailed View of the buckle and means for attachingit to the band. Figs. 4 and 4. show the means for fastening the main band around the body. Fig. 5 is a detail of the buckle of Fig. 3. Fig. 6 is aldetail of the buckle of Fig. 4. Fig. 6 is a sectional view of Fig. 4.

In the drawings, A is the supporting-band, and A the auxiliary strap to pass around the limb and assist in holding the pad in place.

B is the coiledhelical-spring pad, having its inner or apex end wound close to'form the surface to rest against the body over the hernia. The coil B when distended is in the form of a cone or a half-sphere. From the outer or larger turn I) the extension I) lies across the diameter of the base and is bent into a loop b and the end of the extension I) terminates with a hook I). The coils at the apex of the spring B are closer than on the bottom.

The band A passes under the loop Z) and be tween it and the ring b and holds this pad in the proper position With respect to the body of the wearer. The strap A passes around the leg and engages with the hook and draws the extension I) inward and downward. This strap A is attached to the band A by a buckle composed of the ring 0 and the tongue,

0 The rin c is lon enou h to receive through it a loop or fold of the belt A and so narrow that when thetongue c is thrust under the fold of the belt and pulled taut the loop of the belt is sharply bent around the tongue and in bothdirections out from the middle line of the ring. At one end of the ring is a hook nearly closed but open sufliciently to permit the ring G to pass into it and turn within it.

The tongue 0 is provided at one end with a square ring 0, across which is a sliding bar 0. The sliding cross-bar c is preferably made concave on the lower side at c. The same construction is shown in detail in Fig. 6 and adapted to fit partially around the bar 0 of the buckle, so that when the bar 0 is slipped down onto the bar 0 a strap placed between them is held firmly. The double buckle thus formed enables the wearer to adjust the part 0 along the band A and the strap A and dispenses entirely with buckles having pointed tongues or tongues requiring perforations through the strap.

At one end of the strap A is a buckle formed in every respect similar to the part 0, with its cross-bar c. The part 0 which forms the tongue 0 is, however, omitted and the ring 0' engages with a clasp D. The clasp D is a triangular-shaped ring having a central crossbar d, by means of which it is held within a fold of the band A. The irregular form of the ring D permits it to he slipped through the ring 0' and turned, so as to prevent its escaping from claspin g position so long as the band is tight around the wearer. The entire clasp employed to unite the ends of theband is formed of the two parts 0' and D.

To use the buckle O or C, the strap is passed through the buckle over the bar 0, (c in Fig. 6,) and its free end passes back under the bar and between it and the bar 0 (c in Fig. 6.) When strain is put on the strap, it draws the bar 0 down against the bar 0 and causes it to firmly hold the end of the strap.

ward pressure on the band, without anymeans 1 for holding it against the natural tendency tomove downward and out of position.

The advantage of my construction of the whole truss is its extreme simplicity and cheapness, together with the manner of attaching the band and the pad and adjusting them properly to accomplish the purposes I have hereinbefore set torth.

What I claim is- 1. In atruss, a coiled-wire pad having the 'tion in the presence of two witnesses.

extension of its lower turn passed across the diameter of the base and a band to pass under the limb and attach to the free end of said extension, substantially as'described.

2'. A pad for trusses, consisting of a coil of wire formed into hemispheric shape, having the turns at the pressure end wound closer than those at the place of attachment to the belt and adapted to form the surface to rest against the body and having the extension of its lower turn passed across the diameter of the base and terminating in a hook, whereby it is adapted to be engaged with the strap A, substantially as and for the purpose described.

3. In a truss, a coiled-wire pad having an extension of its lower turn passed across the diameter of the base, a supportingaband, and

a ring adapted to hold said band to the ex-.

tension of the spring, substantially as de- 1 scribed.

to a main band,-consisting of thebuc'k'le C, the

bar 0 and the ringfc pivoted to said buckle,

substantially as described.

In testimony whereof I sign this specifica- I-IERBERT P. EWELL. VVi-tnessesz' L1LLY A. BLISS, JosEPH REIMER.
